Prior research suggests that exposure to elementary classrooms
characterized by high levels of student aggression may contribute to the
development of child aggressive behavior problems. To explore this process
in more detail, this study followed a longitudinal sample of 4,907
children and examined demographic factors associated with exposure to
high-aggression classrooms, including school context factors (school size,
student poverty levels, and rural vs. urban location) and child ethnicity
(African American, European American). The developmental impact of
different temporal patterns of exposure (e.g., primacy, recency,
chronicity) to high-aggression classrooms was evaluated on child
aggression. Analyses revealed that African American children attending
large, urban schools that served socioeconomically disadvantaged students
were more likely than other students to be exposed to high-aggressive
classroom contexts. Hierarchical regressions demonstrated cumulative
effects for temporal exposure, whereby children with multiple years of
exposure showed higher levels of aggressive behavior after 3 years than
children with primacy, less recent, and less chronic exposure, controlling
for initial levels of aggression. Implications are discussed for
developmental research and preventive interventions.Members of the Conduct Problems Prevention Research Group
